Synthes 401.818.96 2.0MM TI Cortex Screw Self Tapping 18MM

Synthes 2.0mm Titanium Cortex Screw | Self-Tapping | 18mm Length | 401.818.96

The Synthes 401.818.96 is a premium micro-fixation implant engineered for high-performance stabilization in dense cortical bone. Manufactured from commercially pure Titanium (Ti), this screw provides superior biocompatibility and is the material of choice for patients with metal sensitivities. With a 2.0mm diameter and an 18mm length, it is a vital component of the Synthes Modular Hand System, designed to provide stable anchorage in the metacarpals, phalanges, and midface.

The self-tapping distal tip is a critical efficiency feature; precision-machined cutting flutes allow the screw to carve its own thread path as it is advanced into a $1.4\text{mm}$ pilot hole. This eliminates the separate tapping step, reducing operative time and minimizing mechanical stress on fragile bone fragments.

Technical & Clinical Advantages

• Advanced Titanium Biocompatibility: Titanium promotes excellent soft-tissue tolerance and minimizes the risk of post-operative allergic reactions. Its non-ferromagnetic properties allow for high-fidelity MRI/CT imaging with significantly reduced metal artifact compared to stainless steel.

• Self-Tapping Precision: The integrated cutting tip reduces the number of surgical steps. By eliminating manual tapping, the surgeon maintains better tactile feedback during insertion, which is crucial when fixing small, delicate fragments.

• Optimized Thread Pitch: The $0.6\text{mm}$ pitch is specifically calibrated for the dense cortical bone of the hand and face, providing high pull-out resistance and stable "interference fit" fixation.

• Low-Profile Cruciform Head: The 3.5mm head is designed to sit flush within Synthes Modular Hand plates and 2.0mm straight plates, reducing the risk of palpable hardware or tendon/ligament irritation in subcutaneous areas.

• Extended Reach (18mm): The 18mm length is ideal for bicortical fixation in the metacarpals or for anchoring bone grafts where a deeper thread purchase is required.

Applications

• Hand & Wrist Surgery: Fixation of metacarpal shaft fractures, phalangeal osteotomies, and carpal fusions.

• Craniomaxillofacial (CMF) Surgery: Stabilization of mandibular fractures, orbital rim repairs, and reconstructive bone grafting.

• Podiatric Surgery: Fixation of forefoot fractures and small-bone osteotomies of the hallux.

• Pediatric Orthopedics: Stabilization of small bone fragments where low-profile, biocompatible hardware is preferred.
